lo/w96 Filed July 28, 1960 United States Patent() 3,116,517 CNTINUUS RUN SLIVER CANS James H. Perry, 172 Kilburn St., Fall River, Mass. Filed July 28, 1960, Ser. No. 45,854 2 Claims. (Cl. 19-157) This invention relates to textile machinery, and more particularly to an improved sliver can for textile sl1vers.

The object of the invention -is 4to provide improved sliver cans which `are constructed so that the slivers can be held in such a position that a continuous operation of the textile machinery can be accomplished.

Another object of the invention is to provide an improved sliver can wherein continuous runs from one can to another can be made so that the machinery can have more etlicient and increased production as well as more uniform quality.

A further object of the invention is to provide a sliver can which is extremely simple and inexpensive to manufacture.

Gther objects and advantages will be apparent during the course of the following description.

In the accompanying drawings, forming a part of th1s application, and in which like numerals are used to designate like parts throughout the same.

FIGURE l is a fragmentary sectional view illustrating the present invention.

FIGURE 2 is a fragmentary sectional view illustrating further details of the present invention.

FIGURE 3 is a sectional view taken on the line 3 3 of FIGURE l.

FIGURE 4 is a perspective view of the spring clip for attachment to the outside of a can.

FIGURE 5 is an elevational view.

FIGURE 6 is a fragmentary sectional view illustrating a modiiied can.

FIGURE 7 is a sectional view taken on the line 7-7 of FIGURE 6.

FIGURE 8 is a fragmentary elevational view illustrating the modification of FIGURES `6 and 7.

Referring in detail to the drawings, and more particularly to FIGURES l through 5 of the drawings, the numeral 1li indicates `a support member and the numeral 11 indicates a plurality of sliver cans on the support member Iii, and as shown in the drawings each of the cans 11 embodies a horizontally disposed botto-m wall 12 as well as an upstanding continuous side wall 13.

Arranged contiguous to the inner surface of the side Wall 13 is a pair of vertically disposed spaced parallel rods or sticks 1li, and the upper ends of the rods 14 are inclined or beveled as indicated by the numeral 15. These pair of rods 14 coact to deine therebetween a longitudinally extending vertically disposed guide way or VVspace 16 whereby a portion of the sliver 17 can travel or be guided through the space 16 as later described in this application.

The numeral 1S indicates a clip which is arranged contiguous to the outer surface ofthe wall 13, and the clip 1E is positioned adjacent the -top of the can 11. As shown in FIGURE 4 for example, each clip 1S includes an end portion 19 which is provided with a slot 2.41, and each clip 13 further includes an intermediate outwardly bowed or arcuate section 21 as well as an end section 2.2. A securing element such as a screw 23 extends through the slot 20 and through the wall 13 and into engagement with one of the rods 14. Another securing element 2e is adapted to extend through the wall 13 and into engagement with the other rod 14 (i.e. the rod is not engaged by 'a screw 23) whereby these securing elements help maintain the rods in their proper spaced apart position with respect to each other.

lIn FIGURE 1 the numeral 25 indicates a portion of 3,116,517 Patented Jan. 7, 1964 ICC a conventional textile machine which includes the usual rolls 26 and 27.

Referring now to FIGURES 6, 7 and 8 there is illustrated a modiiied `sliver can 2S which is adapted to be used in lieu of the cans 11, and as shown in the drawings the can 2S includes a horizontally disposed bottom wall 29 as well as -an upstanding side Wall Sii. The side wall 30 is provided with a longitudinally extending vertically disposed ot-set portion 31 which defines a tapering channel or groove 32, and as shown in the drawings, the lower portion of the channel 32 is smaller as indicated by the numeral 33 than the upper portion 34. It is to be understood that as shown in FIGURES 6, 7 and 8 a clip such as the clip 21S is mounted on the outside of the can 28, and this clip 1S is secured in place as for example by means of the securing element or screw 23 rwhich extends through the slot 2d.

From the foregoing, it is apparent that there has been provided a can arrangement for a textile apparatus such as Ia sliver lap machine and it will be seen that accordin to the present invention there has been provided continuous run sliver cans. The can will run in cards, lap winders, draw frames and the like. As shown in the drawings, the sliver 17 is coiled in such a way as to leave only a small opening in the center of the can for air as indicated by the numeral 3S, -FiGU-RE 3. The spring member or clip 1S serves to hold the sliver 17 on the outside of the can such as the can 13, and a clip such as the clip 18 may also be used in conjunction with a can such as the can 2S. Inserts can be attached to any can, such as the inserts 14, or as shown in FIGURES `6, 7 and 8 a continuous run sliver can can be made up without inserts as provided by the channel or portion 31. As shown in the drawings the spring member or clip 1S serves to hold the sliver such as the sliver 17, and the screw or securing element 23 extends through the slot 2G in the member 1S and also engages the insert or rod 14 so that the securing element 23 functions in a dual capacity, that is it retains the clip 18 in place and also retains the insert or rod 14 in place. Due to the provision of the bayonet slot 2d, the spring 13 can be put on without the necessity of taking the screw out. As shown in the drawings, the sliver coils towards the outside of the can. In FIGURES 6 and 7 there is illustrated a completely new can Zit with a grooved portion 32 and this grooved portion or track 32 serves the same purpose as the previously described track 16 defined between the inserts 14. Thus, in FIG- URES 1 through 5 there is illustrated a method of modifying existing cans by adding the inserts 1d and the clip 1" so that the present invention can be carried out, while in FIGURES 6, 7 and 8 there is illustrated a completely new can which is initially formed with the groove 32 that functions as a guide way for the sliver 17. A clip or member 13 may also be used on the outside of the can 23 in the same manner as shown in FIGURES 1 through 5.

F.Ehe inserts or rods 1dare held in place by the securing elements 23 and 24 and these rods may be approximately one `and one-quarter inches in diameter. The clip 1S serves to hold the sliver in proper position on the outside of the can, and the cans can be made to lit the diameters or lengths required.

Thus, 4it will be seen that there has been provided in FIGURES l through 5 cans with two sticks or inserts 1d which can be made `of a suitable material such as wood, metal, plastic or the like and these inserts are positioned within the cans so as to provide the groove or track 16 for the sliver 17 so that the sliver can be held in position, and as shown in FIGURE l, the can 11 at the left side of FIGURE l is arranged so that the end of the sliver 17 can be attached to the beginning of the sliver in the can shown in the center of FIGURE l, and the sliver from the can in the center of FIGURE l can be attached to the end of the sliver in the can on the right side oli Fl"- URE 1 so that a continuous operation can be accomplished.

At the present time it is impossible to have two ends of sliver outside of the cans because of pressure. Thus, the sliver cannot be held in position since it will break and a break in the sliver means defective material as well as loss of time and expense. At the present time sliver is fed to machines such as the machines 2S and when a can empties the machine stops which causes a loss in production and at the present time it is impossible for an operator to piece the strands of sliver together as the can is emptied. Thus, an operator or person has to take care of more than one machine and some of these machines have from sixteen to sixty or more cans so that the machines are constantly being stopped time and time again. With the improved can of the present invention, a person can piece as many cans as he or she has room for, since as the first can runs out of siiver, it has already been i'eced or spliced to the second can and the second to the third and so forth, so that there is a continual run from one to the other which insures that there will be greater production and a more uniform quality.

In use, an empty can is positioned to receive the sliver that is delivered by an adjacent machine and the sliver end portion is disposed between the inserts or rods 14 with the end held under the clip 18, in the first form of the invention shown in FTGURES 1 to 5. The can is then spun so that the loops of sliver pile up inside the can but do not cntangle with the portion of the sliver disposed between the inserts or rods 14 for the reason that the rods 14 shield the end portion of the sliver. In the form of the invention shown in FIGURES 6 to 8, the grooved portion 32 serves the same purpose as the rods 14.

With reference to FIGURE 1, after the cans are filled and are moved to another machine for removal of the sliver, an end portion of the sliver, as at X, in one can, is joined to the end portion of the sliver, as at Y, in an adjacent can by manually opening the sliver of one end portion and inserting the sliver of the other end portion into the opened sliver, and then rolling the combined sliver end portions between the hands to intermingle the fibers thereof.

Minor changes in shape, size and rearrangement of details coming within the held of invention claimed may be resorted to in actual practice, if desired.
